It sounds like you are experiencing burnout at work. It's important to take a step back and evaluate your situation before making any rash decisions. Consider speaking with your manager or HR about how you are feeling, as they may be able to offer support or make adjustments to your workload. It's also worth exploring ways to reignite your passion for your work, such as taking on new projects or seeking opportunities for growth and development. Leaving a job should be a carefully considered decision, so make sure to weigh your options before making a final choice.
